How does carbon give the soil power to absorb moisture t Digitized by Google 83 Tsx toiii. sorbentB in nature ; and it has been proved by ac- curate experiment that peaty Boils absorb moisture with greater rapidity, and part with it more slowly than any other kind. 4. Carbon in the soil renders it warmer, because it darkens its color. Black sur&ces absorb more heat than light ones, and a black coat, when worn in the sun, is warmer than one of a It^ter color. By mixing carbon with the soil, we d...arken its color, and render it capable of absorbing a greater amount of heat from the sun's rays. It will be recollected that, when v^etable matter decomposes in the soil, it produces certain gases (carbonic acid, etc.), which dther escape into the atmosphere, or are retained in the sdl for the use of plants. The production of these gases is always ac- companied by heat J which, though scarcely percep- tible to our senses, is perfectly so to the growing plant, and is of much practical importance.
